SS-OCT - Swept-source Optical Coherence Tomography

  • The non-invasive SS-OCT uses light waves to obtain three-dimensional images on a micron scale. This technology provides cross-sectional images of tissue structures which provides a valuable instrument in research and diagnostic medicine.

    Imaging is performed through OCT when the interference pattern signals are produced by different scans of wavelength when reflected at different depths using low coherence interferometry.

    Fourier-Domain OCT calculates the depth dependent reflection profiles. Continuously performing this A-scan at different locations creates a two dimensional cross section.

    ADQ32 is a fourth-generation dual-channel 12-bit digitizer with 2.5 GSPS sampling rate. It is is optimized for high-throughput applications and includes peer-to-peer streaming to GPU at a rate of 7 GByte/s. ADQ32 also features an open field-programmable gate array (FPGA) for real-time application support.

    The ADQ14OCT is configured to support variable clocking from the most advanced lasers and supports a laser trig rate of up to 1000 MHz to help produce the most detailed images in a very short time. It is factory-programmed with signal processing typically used in SS-OCT applications, providing real-time FFTs up to 32768 bins, logarithm computations, and multiple configuration options to simplify integration into SS-OCT equipment.

    ADQ14OCT is available with USB3.0, PCIe, and PXIe interfaces.
